Information

Provide the ability to use the createSelector function with a dictionary of selectors. This signature would remove repetitive code when creating view model selectors:

// BEFORE:
export const selectUsersPageViewModel = createSelector(
  selectUsers,
  selectActiveUser,
  selectQuery,
  selectIsLoading,
  (users, activeUser, query, isLoading) => ({
    users,
    activeUsers,
    query,
    isLoading,
  })
);

// AFTER:
export const selectUsersPageViewModel = createSelector({
  users: selectUsers,
  activeUser: selectActiveUser,
  query: selectQuery,
  isLoading: selectIsLoading,
});

Recently, we added a similar feature to the ComponentStore.select method (#3624).
